To what extent can noisy quantum circuits be classically simulated? And at what point is this no longer true, so that one can hope for a quantum advantage? This is a compelling research question. Here, we suggest frames to do so, extending known Monte Carlo methods.

Do Bose-Hubbard type systems have a speed of sound for particle propagation?

scirate.com/arxiv/2601.001…

Yes. This work proves a strikingly simple bound of this kind for particle propagation for generalized Bose–Hubbard models defined on general lattices.

Trump’s immigration crackdown is keeping foreign professionals out Federal authorities are denying more work visas and green cards, vetting social media posts and applying enhanced scrutiny to foreign employees’ credentials.

The Trump administration’s crackdown on legal immigration is making it tougher for doctors, engineers, professors and artists to get permission to work and live in the U.S.

For foreign professionals, the crackdown has meant new levels of anguish and fear.

This is a manuscript I am particularly happy with. It concerns topics I have been working on for my PhD, entanglement theory, going back to the work of Bennett et al. Yet it still has a fresh flavour, relating the subject to modern developments in quantum computing.
